FIELD

The present disclosure relates to the technical field of display, inparticular to a display panel and a display device.

BACKGROUND

After development in recent decades, the technology and process of aliquid crystal display (LCD) increasingly mature, and the LCD hasreplaced a cold cathode fluorescent lamp (CCFL) display to become amainstream product in the field of display.

When the LCD is manufactured in an integrated modularization manner, aframe needs to be additionally installed on a peripheral non-displayregion, or double-faced foam adhesive tape needs to be pasted under thenon-display region, thereby fixing a liquid crystal display panel to aback plate frame of a whole display.

However, the frame or the double-faced foam adhesive tape will producecertain stress on the non-display region, since the non-display regionof the LCD has poor supporting capacity, when the stress acts on theperipheral non-display region, large deformation will be produced and betransmitted to a display region, which, on the one hand, will make aglass substrate at the edge of the display region generate phase delay,resulting in change of a polarization state of emitted light, and on theother hand, will also make the liquid crystal box thickness at the edgeof the display region change, resulting in disordered liquid crystaldistribution, such that the edge of the display region has the lightleakage phenomenon.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to solve the technical problem that a non-display region of aliquid crystal display has poor supporting capacity, such that a lightleakage phenomenon is likely to occur at the edges of a display region,embodiments of the present disclosure provide a display panel and adisplay device.

The detailed description of the display panel and the display deviceaccording to the embodiments of the present disclosure is illustrated indetail below in conjunction with the accompanying drawings. The sizesand shapes of all parts in the accompanying drawings do not reflect truescales, and are only intended to schematically illustrate the content ofthe present disclosure.

FIG. 1 illustrates a schematic top-view structural diagram of a displaypanel according to an embodiment of the present disclosure, and FIG. 2illustrates a cross-sectional diagram along a straight line L1 in FIG. 1.

As shown in FIG. 1 and FIG. 2 , the display panel according to theembodiment of the present disclosure includes:

a first substrate 100;

at least one underlaying structure 101, arranged on the first substrate100 and arranged in a non-display region B of at least one side of adisplay region A of the display panel; and

at least one supporting structure 102, arranged on one side, facing awayfrom the first substrate 100, of the underlaying structure 101.

where the orthographic projection of the supporting structure 102 on thefirst substrate 100 is within a range of the orthographic projection ofthe underlaying structure 101 on the first substrate 100.

In the above display panel according to the embodiment of the presentdisclosure, the underlaying structure and the supporting structure arearranged in the non-display region of at least one side of the displayregion, and the underlaying structure can underlay the supportingstructure, so that the supporting capacity at the non-display region ofthe display panel is improved, the external force impact resistance atthe non-display region of the display panel is improved, and the lightleakage phenomenon at the edges of the display region is reduced.

As shown in FIG. 2 , the orthographic projections of the supportingstructures 102 on the first substrate 100 are within the range of theorthographic projections of the underlaying structures 101 on the firstsubstrate 100, so that it is guaranteed that the underlaying structures101 can underlay the whole supporting structures 102, the situation thatpart of the supporting structures 102 is underlaid with the underlayingstructures 101 while the other part is not underlaid with theunderlaying structures 101 is avoided, thereby avoiding poor supportinguniformity of the supporting structures 102 caused by segment spaces onthe side, facing away from the first substrate 100, of the supportingstructures 102, and thus the supporting capacity of the non-displayregion is guaranteed.

Specifically, in the embodiment of the present disclosure, the abovedisplay panel is preferably a liquid crystal display panel, that is, thedisplay panel may further include a liquid crystal layer. The abovefirst substrate may be an array substrate, namely the underlayingstructure and the supporting structure may be located on the arraysubstrate, or, the above first substrate may further be a color filmsubstrate, namely the underlaying structure and the supporting structuremay further be located on the color film substrate, and the positions ofthe underlaying structure and the supporting structure are not limitedherein.

In specific embodiment, in the embodiment of the present disclosure, theunderlaying structure and the supporting structure may be arranged inthe non-display region of at least one side of the display regionaccording to a light leakage condition in the display region of thedisplay panel. For example, if the light leakage phenomenon only occursat the edge of one side of the display region, the underlaying structureand the supporting structure may be only arranged in the non-displayregion located on the side.

Optionally, in order to guarantee that no light leakage phenomenonoccurs in the edge of each side of the display region, as shown in FIG.1 , the underlaying structure and the supporting structure are arrangedin the non-display region of each side of the display region A.

FIG. 3 a illustrates a schematic top-view structural diagram of adisplay panel, and FIG. 3 b illustrates a schematic cross-sectionaldiagram along a dotted line L3 in FIG. 3 a.

In specific embodiment, as shown in FIG. 3 a and FIG. 3 b , a lightleakage condition of the display panel 302 subjected to stress broughtby gaskets 303 may be detected by placing the display panel 302 on amachine table 301 and arranging the gaskets 303 between the displaypanel 302 and the machine table 301, where the gaskets 303 are locatedon an edge of the display panel 302. In FIG. 3 a , in order to show atop view structure of the gaskets 303 more clearly, part of the gaskets303 shielded by the display panel 302 in the FIG. 3 is represented bydotted lines.

In the embodiment of the present disclosure, the gaskets 303 are adoptedto apply stress on the display panel 302, in specific embodiment, otherdetection methods may further be adopted, for example, press strips maybe placed at edges of the surface of the display panel 302 to applystress on the non-display region, the detection methods for applyingstress are not limited herein, and the detection methods may be selectedaccording to actual conditions.

FIG. 3 c and FIG. 3 d are schematic diagrams of real objects detectedaccording to the above methods. FIG. 3 c illustrates a schematic diagramof a detected display panel without an underlaying structure or asupporting structure. FIG. 3 c illustrates a schematic diagram of adetected display panel of which a non-display region has poor supportingcapacity, and FIG. 3 d is a schematic diagram of the detected displaypanel provided with the underlaying structure and the supportingstructure in the embodiment of the present disclosure.

It can be obviously seen from FIG. 3 c that in the display panel ofwhich the non-display region has the poor supporting capacity, the lightleakage phenomenon is relatively serious near the gaskets 303. Taking alight leakage region on the right of the right gasket 303 as an example,a range of the light leakage region is appropriately marked with an arcin FIG. 3 c , a width d1 of the light leakage region is about 5.5 mm,and a height h1 thereof is about 2.3 mm.

It can be obviously seen from FIG. 3 d that in the display panelaccording to the embodiment of the present disclosure, the light leakagephenomenon is relatively weak near the gaskets 303. Taking a lightleakage region on the right of the right gasket 303 as an example too, arange of the light leakage region is appropriately marked in ahighlighted manner in FIG. 3 d , a width d2 of the light leakage regionis about 3.1 mm, and a height d2 thereof is about 1.0 mm.

Therefore, by comparing the size and light leakage intensity of thelight leakage region in FIG. 3 c and the size and light leakageintensity of the light leakage region in FIG. 3 d , it can be obviouslyseen that the display panel according to the embodiment of the presentdisclosure can obviously reduce the light leakage phenomenon at theedges of the display panel.

Specifically, as shown in FIG. 2 , the above display panel according tothe embodiment of the present disclosure further includes: a color lightfilter layer 103 located in the display region A.

The color light filter layer 103 includes sub-pixel color resistors inat least three colors (e.g., in FIG. 2 , R represents a sub-pixel colorresistor in red, G represents a sub-pixel color resistor in green and Brepresents a sub-pixel color resistor in blue), so that the displaypanel may emit color light.

The underlaying structure 101 includes: color resistor structureslocated on a same layer and made of the same material with the sub-pixelcolor resistors in at least one color.

The color resistor structures in the underlaying structure 101 arelocated on the same layer and made of the same material with thesub-pixel color resistors, in the process of a manufacturing technique,the color resistor structures and the sub-pixel color resistors may bemanufactured by the same technique, so as to reduce the manufacturingtechnique and lower the manufacturing cost.

In specific embodiment, as shown in FIG. 2 , the above display panelaccording to the embodiment of the present disclosure includes: aplurality of spacers located in the display region A. The spacers arelocated on the side, facing away from the first substrate 100, of thecolor light filter layer 103.

The plurality of spacers are divided into a plurality of main spacers106 a and a plurality of sub-spacers 106 b.

A sum of a height of the supporting structure 102 and a thickness of theunderlaying structure 101 is greater than a sum of a height of the mainspacer 106 a and a thickness of the color light filter layer 103.

As shown in FIG. 2 , that is, when other film layers on the firstsubstrate 100 have the consistent thickness, the thickness of all thefilm layers on the first substrate 100 in the non-display region B isgreater than the thickness of all the film layers on the first substrate100 in the display region A, so that after the first substrate 100 and asecond substrate are aligned later, the supporting structure 102 will becompressed, so as to support the first substrate 100 and the secondsubstrate 200 therebetween to guarantee the supporting capacity at thenon-display region of the display panel.

In specific embodiment, in order to guarantee the consistent boxthickness at the display region A and the non-display region B of thedisplay panel after alignment and prevent a poor display phenomenon, thesum of the height of the supporting structure 102 and the thickness ofthe underlaying structure 101 may be set to be slightly greater than thesum of the height of the main spacer 106 a and the thickness of thecolor light filter layer 103.

In practical application, the above display panel according to theembodiment of the present disclosure further includes: the secondsubstrate 200 arranged opposite to the first substrate 100.

As shown in FIG. 1 , the display panel further includes: a plurality ofpixel units P arranged in an array in the display region A, and aplurality of data lines (not shown in the figure) located on the side,facing the first substrate 100, of the second substrate 200 extending ina first direction Y and arranged in a second direction X.

The non-display region B is divided into two first sub-regions B1 andtwo second sub-regions B2; wherein the two first sub-regions B1 arelocated on two sides of the display region A in the first direction Y,and the two second sub-regions B2 are located on two sides of thedisplay region A in the second direction X; and the second direction isperpendicular to the first direction.

The first sub-regions B1 and the second sub-regions B2 each include anunderlaying structure.

Specifically, in order to guarantee that no light leakage phenomenonoccurs at the edge of each side of the display region, strip-shapedspacers 102 a may be arranged in the two first sub-regions B1 and thetwo second sub-regions B2 as shown in FIG. 1 .

Specifically, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 5 and FIG. 6 , the underlayingstructure includes at least two color resistor structures. As shown inFIG. 5 , the underlaying structure may include a color resistorstructure 101 a, a color resistor structure 101 b and a color resistorstructure 101 c. As shown in FIG. 6 , the underlaying structure mayinclude a color resistor structure 101 a and a color resistor structure101 b.

Orthographic projections of the color resistor structures which belongto a same underlaying structure on the first substrate have anoverlapping region. As shown in FIG. 5 , the orthographic projection ofthe color resistor structure 101 a, the orthographic projection of thecolor resistor structure 101 b and the orthographic projection of thecolor resistor structure 101 c on the first substrate 100 have theoverlapping region, that is, the color resistor structures 101 a, 101 band 101 c are arranged in a laminated manner. As shown in FIG. 6 , theorthographic projection of the color resistor structure 101 a and theorthographic projection of the color resistor structure 101 b on thefirst substrate have the overlapping region, that is, the color resistorstructures 101 a and 101 b are arranged in a laminated manner, so thatdifferent numbers of color resistor structures may be laminated toobtain the underlaying structure with different thicknesses. In specificembodiment, the number of the color resistor structures in theunderlaying structure may be determined according to actual demands, or,the height of the color resistor structures may also be adjusted througha halftone mask.

In the process of a manufacturing technique, different masks may beadopted to respectively manufacture the sub-pixel color resistors indifferent colors, figures of the color resistor structures may be set atpositions, corresponding to the non-display region, of at least twomasks, and therefore the color resistor structures and the sub-pixelcolor resistors in the display region may be manufactured through thesame composition technique.

Specifically, as shown in FIG. 5 , the color resistor structure 101 aand the sub-pixel color resistor in red in the display region A may bemanufactured through a same composition technique, the color resistorstructure 101 b and the sub-pixel color resistor in blue in the displayregion A may be manufactured through a same composition technique, andthe color resistor structure 101 c and the sub-pixel color resistor ingreen in the display region A may be manufactured through a samecomposition technique. Therefore, three layers of color resistorstructures (101 a, 101 b and 101 c) arranged in a laminated manner maybe obtained through the three times of composition technique for thesub-pixel color resistors.

In specific embodiment, in the display panel according to the embodimentof the present disclosure, as shown in FIG. 7 , orthographic projectionsof the color resistor structures (such as 101 a, 101 b and 101 c in FIG.7 ) which belong to a same underlaying structure on the first substrate100 do not overlap.

In the actual technique process, the same mask may be adopted tomanufacture the sub-pixel color resistors in different colors. Takingthe structure shown in FIG. 7 as an example, figures of sub-pixels areset at the positions, corresponding to the display region, of the mask,and figures of the color resistor structures are set at the positions,corresponding to the non-display region, of the mask. In themanufacturing process, the mask may be adopted to manufacture thesub-pixel color resistors in red first so as to form color resistorstructures in red 101 c in the non-display region, then, the mask isstaggered by the distance of one pixel unit for manufacturing thesub-pixel color resistors in blue so as to form color resistorstructures in blue 101 b in the non-display region, and finally, themask is staggered by the distance of one pixel unit again formanufacturing the sub-pixel color resistors in green so as to form colorresistor structures in green 101 a in the non-display region.

This is only for illustration herein, in the actual technique process,the mask may also be staggered by the distance of more pixel units formanufacturing the sub-pixel color resistors in different colors, and atotal staggering distance is integer multiples of dimensions of thepixel units. Moreover, in practical application, the color order of themanufactured sub-pixel color resistors may also be determined accordingto actual needs, which is not limited herein.

In addition, different masks may also be adopted to respectivelymanufacture the sub-pixel color resistors in different colors, and themanufacturing technique is not limited herein.

Compared with the display panel shown in FIG. 5 and FIG. 6 , in thedisplay panel shown in FIG. 7 , the orthographic projections of thecolor resistor structures which belong to a same underlaying structureon the first substrate 100 do not overlap.

In the manufacturing process, the color resistor structures and thesub-pixel color resistors in the display region may adopt the samecomposition technique, and the same mask is adopted to manufacture thecolor resistor structures in different colors, so that the number of themasks can be saved, and the manufacturing cost of the technique islowered. In practical application, on the basis of meeting requirementsof the underlaying structure and in order to lower the technique cost asmuch as possible, the embodiment of the present disclosure preferablyadopts the structure shown in FIG. 7 or FIG. 6 .

Specifically, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 8 , in each first sub-regionB1, the underlaying structure 101 includes the color resistor structuresin three colors. In each second sub-region B2, the underlaying structure101 includes the color resistor structures in one color. For example,the second sub-region B2 on the left in FIG. 8 includes a plurality ofcolor resistor structures in red, and the second sub-region B2 on theright in FIG. 8 includes a plurality of color resistor structures ingreen.

In the underlaying structure 101 of each first sub-region B1, the colorresistor structures are arranged in one row in the second direction X,and the color resistor structures in three colors are alternatelyarranged.

In the underlaying structure 101 of each second sub-region B2, the colorresistor structures are arranged in one row in the first direction Y.

As shown in FIG. 8 , generally, the pixel units P in the display regionA are arranged in an array, a width of each color resistor structure ineach first sub-region B1 in the second direction X may be set to be thesame as a width of the pixel unit P in the second direction X, a widthof each color resistor structure in each second sub-region B2 in thefirst direction Y may be set to be the same as a width of the pixel unitP in the first direction Y, and accordingly the underlaying structure inthe non-display region can be conveniently arranged.

In specific embodiment, the underlaying structure in each secondsub-region may also be an integrated structure, that is, the underlayingstructure is composed of one color resistor structure. For example, onlyone color resistor structure in red may be arranged in the secondsub-region on the left, only one color resistor structure in green maybe arranged in the second sub-region on the right, and color resistorstructures in other colors may also be arranged in the secondsub-regions, which is not limited herein.

More specifically, in the above display panel according to theembodiment of the present disclosure, also referring to FIG. 8 , thecolor resistor structures and first sub-pixel color resistors areconnected into an integrated structure.

The first sub-pixel color resistors are sub-pixel color resistorslocated at edges of the display region A, and the first sub-pixel colorresistors and the color resistor structures are adjacent and have thesame color.

In the display region A, the pixel units P in three colors in each roware alternately arranged in the second direction X, the pixel units P ineach row have the same color in the first direction Y. The colorresistor structures in the non-display region are arranged to be anintegrated structure with the first sub-pixel color resistors, and thepixel units at the farthest edges of the display region just need toextend to the non-display region, which is more conductive tocomposition of the color resistor structures in the non-display region.

As shown in FIG. 8 , in the actual technique process, three differentmasks may be adopted to respectively manufacture the sub-pixel colorresistors in different colors. In the mask for manufacturing thesub-pixel color resistors in red, figures of the underlaying structureare set in the positions corresponding to the two first sub-regions B1and the second sub-region B2 on the left. Based on the same principle,figures of the underlaying structure may be set in the masks formanufacturing the sub-pixel color resistors in blue and the sub-pixelcolor resistors in green, so that the underlaying structure in thenon-display region are manufactured while the sub-pixel color resistorsin the display region are manufactured.

In specific embodiment, in the above display panel according to theembodiment of the present disclosure, as shown in FIG. 9 , in each firstsub-region B1, the underlaying structure 101 includes the color resistorstructures in three colors; and in each second sub-region B2, theunderlaying structure 101 includes the color resistor structures inthree colors.

In the underlaying structure 101 of each first sub-region B1, the colorresistor structures are arranged in one row in the second direction X,and the color resistor structures in three colors are alternatelyarranged.

In the underlaying structure 101 of each second sub-region B2, the colorresistor structures are arranged in one row in the second direction X,and the color resistor structures in three colors are alternatelyarranged.

As shown in FIG. 9 , in the first sub-regions B1 and the secondsub-regions B2, the color resistor structures are alternately arrangedin the second direction X, and accordingly in the actual techniqueprocess, the same mask may be adopted to manufacture the color resistorstructures in different colors.

In practical application, the underlaying structure in the non-displayregion may also be arranged to be composed of only one color resistorstructure, that is, the underlaying structure may be an integratedstructure. Moreover, the underlaying structure may be arranged atpositions, extending to the non-display region, of the display region,as shown in FIG. 8 . Or, the underlaying structure may also be arrangedat positions other than the positions, extending to the non-displayregion, of the display region, as shown in FIG. 9 . Specificdistribution of the underlaying structure in the non-display region isnot limited herein, and the specific distribution condition of theunderlaying structure may be set according to actual demands.

Specifically, as shown in FIG. 2 , the above display panel according tothe embodiment of the present disclosure further includes: a shadinglayer 104 located between the underlaying structure 101 and the firstsubstrate 100, and a flat layer 105 located on one side, facing awayfrom the first substrate 100, of the underlaying structure 101.

In specific embodiment, the shading layer 104 extends into thenon-display region B, which may prevent light leakage at the non-displayregion and guarantee the display effect of the display panel. Theshading layer 104 located in the non-display region B may furtherunderlay the supporting structure 102 and further improve the supportingcapacity at the non-display region of the display panel.

The flat layer 105 extends into the non-display region B, which mayflatten the film layers in the non-display region B. An orthographicprojection of the flat layer 105 on the first substrate 100 and anorthographic projection of the underlaying structure 101 on the firstsubstrate 100 have an overlapping region. Accordingly, part of the flatlayer 105 extending into the non-display region B may further underlaythe supporting structure 102 and further improve the supporting capacityat the non-display region of the display panel.

In addition, in the embodiment of the present disclosure, theunderlaying structure is composed of color resistor structures locatedon the same layer and made of the same material with the sub-pixel colorresistors in at least one color, which is an implementation in theembodiment of the present disclosure. In practical application, theunderlaying structure may also be located on the same layer and made ofthe same material with other film layers, such as the flat layer or theshading layer, or, the underlaying structure may also be separatelymanufactured in the non-display region through a composition technique,which is not limited herein.

Further, In the above display panel according to the embodiment of thepresent disclosure, as shown in FIG. 4 , an end surface of one side,facing away from the first substrate 100, of the supporting structure102 is in contact with a surface of one side, facing the first substrate100, of the second substrate 200, so that the supporting capacity at thenon-display region of the display panel may be further improved, theexternal force impact resistance at the non-display region of thedisplay panel may be further improved, and the light leakage phenomenonat the edges of the display region is reduced.

In specific embodiment, the thickness of the underlaying structure 101may be determined in combination with the height of the supportingstructure 102, so as to guarantee that the end surface of the side,facing away from the first substrate 100, of the supporting structure102 is in contact with the surface of the side, facing the firstsubstrate 100, of the second substrate 200.

In practical application, in the above display panel according to theembodiment of the present disclosure, also referring to FIG. 4 , thenon-display region B further internally includes: a metal layer 201located on the side, facing the first substrate 100, of the secondsubstrate 200.

An orthographic projection of each supporting structure 102 on thesecond substrate 200 is within a range of an orthographic projection ofthe metal layer 201 on the second substrate 200.

That is, the supporting structures 102 in the non-display region B areall located on the metal layer 201, therefore, the consistentcompression amount of the supporting structures 102 may be guaranteed,and the uniformity of the supporting capacity in the non-display regionB is good.

Specifically, the above metal layer may be a gate layer or asource-drain metal layer or other film layers, which is not limitedherein, as long as each supporting structure 102 supports the same metallayer. It should be noted that the supporting structure 102 is not indirect contact with the metal layer 201, and an insulating layer 203 mayalso be arranged between the metal layer 201 and the supportingstructure 102.

In addition, the supporting structures 102 in the non-display region Bmay be all located in regions outside figures of the metal layer 201,which can also make the uniformity of the supporting capacity in thenon-display region B good.

In specific embodiment, in the above display panel according to theembodiment of the present disclosure, as shown FIG. 4 , the non-displayregion B further internally includes: a frame sealant 202 locatedbetween the first substrate 100 and the second substrate 200.

The frame sealant 202 is located at an edge of the display panel.

The underlaying structure 101 is located between the frame sealant 202and the display region A, and a space C exists between the underlayingstructure 101 and the frame sealant 202.

The first substrate 100 and the second substrate 200 are fixed throughthe frame sealant 202. To guarantee that the underlaying structure 101does not affect diffusion of the frame sealant 202 and to guarantee thepackaging effect of the display panel, it is necessary to guarantee thatthe a space C exists between the underlaying structure 101 and the framesealant 202.

Specifically, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 4 , the space C between theunderlaying structure 101 and the frame sealant 202 is greater than asum of position precision of the frame sealant 202 and diffusionprecision of the frame sealant 202 as well as position precision of theunderlaying structure 101.

In the case that the different masks are adopted to respectivelymanufacture the sub-pixel color resistors in different colors, the abovespace C between the underlaying structure 101 and the frame sealant 202needs to be greater than a sum of the position precision of the framesealant 202 and the diffusion precision of the frame sealant 202 as wellas the position precision of the underlaying structure 101.

In the case that the same mask is adopted to manufacture the sub-pixelcolor resistors in different colors, the above space C is equal to adifference value between a distance from the frame sealant 202 to anedge of the display region A and the dimensions of N pixel units,wherein N is an integer. The space C needs to be greater than the sum ofthe position precision of the frame sealant 202 and the diffusionprecision of the frame sealant 202 as well as the position precision ofthe underlaying structure 101.

The position precision of the frame sealant may be understood as adifference between a designed position and an actual position of theframe sealant.

In the specific technique process, edges of the first substrate (or thesecond substrate) are coated with the colloidal frame sealant first, andthe frame sealant is solidified after the first substrate and the secondsubstrate are aligned. In the process of coating the frame sealant, theframe sealant will diffuse in a certain region due to its fluidity, andthe diffusion precision of the frame sealant may be understood as thesize of a diffusion region of the frame sealant.

The position precision of the underlaying structure may be understood asa difference between a designed position and an actual position of theunderlaying structure.

Also referring to FIG. 4 , a distance between an edge of the side, awayfrom the display region A, of the supporting structure 102 farthest fromthe display region A and an edge of the side, away from the displayregion A, of the underlaying structure 101 is D. Also referring to FIG.7 , considering that each underlaying structure 101 may be composed ofthe plurality of staggered color resistor structures, the distance Dneeds to be greater than the dimensions of the pixel units, so as toguarantee that the supporting structure 102 can be located on the flatunderlaying structure 101 and guarantee the uniformity of supportingcapacity.

In the actual technique process, after the first substrate 100 and thesecond substrate 200 are aligned, the frame sealant 202 needs to besolidified in an illumination way. In order to avoid light leakage atthe non-display region, the shading layer 104 is arranged on one side ofthe first substrate 100, therefore, the metal layer 201 and theinsulating layer 203 on the second substrate 200 may be patterned, so asto form a plurality of through holes in the position corresponding tothe frame sealant 202, and one side of the second substrate 200 may beilluminated to solidify the frame sealant 202.

As shown in FIG. 4 , a distance between the adjacent supportingstructures 102 is E. The distance E may be determined in combinationwith the position where the supporting structure 102 can be accommodatedin the display panel, for example, the figure distribution condition ofthe metal layer 201 may be considered. For example, the distance E maybe 100 μm to 1,000 μm, and the distance E may also be set according toactual conditions, which is not limited herein.

Specifically, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 4 , the display region Afurther internally includes: a plurality of spacers (e.g., spacers 106 aand 106 b in FIG. 4 ) located on the side, facing away from the firstsubstrate 100, of the color light filter layer 103.

The supporting structure 102 is located on the same layer and made ofthe same material with the spacers.

In the process of a manufacturing technique, the supporting structure102 and the spacers may be manufactured through the same compositiontechnique so as to save technique steps and lower the manufacturingcost.

Specifically, as shown in FIG. 4 , the spacer capable of making contactwith surfaces of both the first substrate 100 and the second substrate200 is a main spacer 106 a, and the spacer only in contact with thesurface of the first substrate 100 and not in contact with the surfaceof the second substrate 200 is a sub-spacer 106 b. Since the underlayingstructure 101 is arranged at the position of the supporting structure102, the height of the supporting structure 102 may be set the same asthe height of the sub-spacer 106 b, and by adjusting the thickness ofthe underlaying structure 101, the supporting structure 102 can supportthe first substrate 100 and the second substrate 200 therebetween.

In specific embodiment, the supporting structure 102 and the sub-spacer106 b may be manufactured through the same composition technique, or,the supporting structure 102, the main spacer 106 a and the sub-spacer106 b may also adopt a halftone mask to realize manufacture through thesame composition technique.

In specific embodiment, in the above display panel according to theembodiment of the present disclosure, the above supporting structureincludes: strip-shaped spacers 102 a, and at least one strip-shapedspacer 102 a extends in the first direction Y or the second direction X.

If spaces allow, by adopting the strip-shaped spacers 102 a extending inthe first direction Y or the second direction X, the strip-shapedspacers 102 a have a large supporting range and may make the supportingeffect of the non-display region B good.

Specifically, as shown in FIG. 1 , positions of M in the display regionA represent positions of the main spacers, and positions of S representpositions of the sub-spacers. In specific embodiment, distribution ofthe main spacers M and the sub-spacers S may be determined according toactual conditions, which is not limited herein. Specifically, at leasttwo rows of strip-shaped spacers may be arranged, and the number of thestrip-shaped spacers may be determined according to required contactdensity.

In specific embodiment, in the display panel according to the embodimentof the present disclosure, as shown in FIG. 1 , gaps between theplurality of pixel units P in the second direction X are first gaps.

In each second sub-region B2, the strip-shaped spacers 102 a extend inthe second direction X and are arranged in an array, and orthographicprojections of at least part of the strip-shaped spacers 102 a on aplane perpendicular to the second direction X have overlapping regionswith orthographic projections of the first gaps on the planeperpendicular to the second direction X. Dotted lines L2 in FIG. 1represent straight lines where the first gaps are located.

In the technique manufacturing process, after the first substrate ismanufactured, rubbing alignment needs to be performed on an alignmentlayer on the surface of the first substrate. Specifically, rollingfriction may be performed by rollers in the second direction X, and inorder to avoid influences of the strip-shaped spacers on the rollers inthe rubbing alignment process and avoid influences of damaged rollers onthe rubbing alignment effect, the strip-shaped spacers 102 a may bearranged at positions, extending to the non-display region, of the firstgaps.

As shown in FIG. 1 , the strip-shaped spacers 102 a in each secondsub-region B2 are all located at positions of the dotted lines L2. Inthe rubbing alignment process, when the rollers roll in the seconddirection X, the rollers make contact with the strip-shaped spacers 102a at positions corresponding to the first gaps, so that it is guaranteedthat the rollers are not in contact with the strip-shaped spacers 102 aat positions corresponding to the pixel units and it is guaranteed thatthe rollers are not damaged at the positions corresponding to the pixelunits, and the display panel can have a good display effect.

Specifically, in each second sub-region B2, values of lengths of thestrip-shaped spacers 102 a in the second direction X are less than orequal to two kinds of values as far as possible. For example, in thestructure shown in FIG. 1 , the lengths of a row of strip-shaped spacers102 a in the first direction Y may be first values, the lengths of theother row of strip-shaped spacers 102 a may be second values, andspecific values of the lengths of the strip-shaped spacers 102 a may beinteger multiples of the dimensions of the pixel units.

To avoid influences of the strip-shaped spacers 102 a on the displayregion A, in each second sub-region B2, a space between the strip-shapedspacer 102 a closest to the display region A and the display region A isgreater than or equal to 0.5 mm.

As shown in FIG. 10 , in each second sub-region B2, only part of thestrip-shaped spacers 102 a are located at positions, extending to thenon-display region, of the first gaps. To lower influences of thestrip-shaped spacers 102 a on a rubbing alignment technique as much aspossible, the row of strip-shaped spacers 102 a extending in the firstdirection Y may be evenly distributed, and it is guaranteed as much aspossible that there are strip-shaped spacers 102 a at the positions ofthe dotted lines L2.

Or, as shown in FIG. 1 , all the strip-shaped spacers 102 a are locatedat the positions, extending to the non-display region, of the firstgaps, so as to lower the influences of the strip-shaped spacers 102 a onthe rubbing alignment technique to the minimum.

In addition, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 11 , in each second sub-regionB2, the strip-shaped spacers 102 a extend in the first direction Y.

Orthographic projections of the strip-shaped spacers 102 a, located inthe same second sub-region B2, on a plane perpendicular to the seconddirection X form a continuous figure.

The orthographic projections of the strip-shaped spacers 102 a, locatedin the same second sub-region B2, on the plane perpendicular to thesecond direction X form the continuous figure, in the process of therubbing alignment technique, the rollers roll in the second direction X,influences of the strip-shaped spacers 102 a on the rollers arerelatively uniform, and thus the influences of the strip-shaped spacers102 a on the rollers are lowered, and the display effect of the displaypanel is guaranteed. To avoid the influences of the strip-shaped spacers102 a on the display region A, in each second sub-region, a spacebetween the strip-shaped spacer closest to the display region and thedisplay region is greater than or equal to 1.5 mm.

Further, in the above display panel according to the embodiment of thepresent disclosure, also referring to FIG. 11 , in each secondsub-region B2, the farther from the display region A, the longer thestrip-shaped spacers 102 a in the first direction, and therefore foreignsubstances may be effectively blocked to be prevented from entering thedisplay region A.

In addition, to avoid the influences of the strip-shaped spacers 102 aon the display region A, in each second sub-region, the space betweenthe strip-shaped spacer closest to the display region and the displayregion is greater than or equal to 1.5 mm.

In practical application, in the above display panel according to theembodiment of the present disclosure, as shown in FIG. 1 , in each firstsub-region B1, the strip-shaped spacers 102 a extend in the seconddirection X.

Orthographic projections of the strip-shaped spacers 102 a, located inthe same first sub-region B1, on a plane perpendicular to the firstdirection Y form a continuous figure.

In each first sub-region B1, the strip-shaped spacers 102 a extend inthe second direction X, so as to effectively block foreign substancesand prevent the foreign substances from entering the display region A.Moreover, the strip-shaped spacers 102 a belonging to the same firstsub-region B1 are arranged in a staggered manner, so as to makeorthographic projections of the strip-shaped spacers 102 a on the planeperpendicular to the first direction Y form the continuous figure, andthe capacity of blocking foreign substances may be further enhanced.Specifically, at least two rows of strip-shaped spacers may be arranged,and the number of the strip-shaped spacers may be determined accordingto required contact density.

Further, in the above display panel according to the embodiment of thepresent disclosure, also referring to FIG. 1 , in each first sub-regionB1, the farther from the display region A, the longer the strip-shapedspacers 102 a in the second direction X, and therefore foreignsubstances may be effectively blocked to be prevented from entering thedisplay region A, and the display effect of the display panel is avoidedbeing affected by the foreign substances entering the display region A.

In each first sub-region B1, values of lengths of the strip-shapedspacers 102 a in the second direction X are less than or equal to twokinds of values as far as possible. For example, the lengths of thestrip-shaped spacers 102 a may be the same, or, the lengths of the firstrow and the third row of strip-shaped spacers may be first values, thelengths of the second row of strip-shaped spacers may be second values.Specifically, the lengths of the strip-shaped spacers may be integermultiples of the dimensions of the pixel units.

In specific embodiment, dimensions of the strip-shaped spacers 102 a atdifferent positions may be determined in combination with specificspaces in the first sub-regions B1 and the second sub-regions B2. Thatis, the lengths of the strip-shaped spacers 102 a in the first directionY or the second direction X may be adjusted according to actualconditions, for example, widths of the strip-shaped spacers 102 a may beset in a range of 20 μm to 80 μm.

In addition, in order to avoid the influences of the strip-shapedspacers 102 a on the display region A, in each first sub-region, a spacebetween the strip-shaped spacer closest to the display region and thedisplay region is greater than or equal to 1.5 mm.

In practical application, in the above display panel according to theembodiment of the present disclosure, a contact density of thesupporting structure in the first sub-regions B1 may be greater than10,000 μm²/mm².

A contact density of the supporting structure in the second sub-regionsB2 may be greater than 5,000 μm²/mm².

The supporting structure may be arranged by adopting the way in FIG. 1 ,FIG. 10 or FIG. 11 , according to contact density requirements of thefirst sub-regions B1 and the second sub-regions B2 as well as figuredistribution conditions of other relevant film layers in the displaypanel, for example, figure distribution of the metal layer isconsidered, and therefore, the display panel has good supportingcapacity at the first sub-regions B1 and the second sub-regions B2.

Moreover, in order to achieve good supporting uniformity at thenon-display region, a uniform shape of the supporting structures in thenon-display region is ensured as much as possible, for example, in FIG.1 , the strip-shaped spacers 102 a have the consistent extendingdirection.

In practical application, in the above display panel according to theembodiment of the present disclosure, a compression amount of thesupporting structure is in a range of 0.1 to 0.3 μm.

Taking the structure shown in FIG. 4 as an example, in the manufacturingprocess, the height of the supporting structure 102 manufactured on thefirst substrate 100 is slightly higher than a distance between the flatlayer 105 and the metal layer 201, a difference between this distanceand the height of the supporting structure 102 is the compressionamount, and therefore, after the first substrate 100 and the secondsubstrate 200 are aligned, the supporting structure 102 will becompressed, so as to support the first substrate 100 and the secondsubstrate 200 therebetween and guarantee the supporting capacity at thenon-display region of the display panel. In addition, too largecompression amount will cause poor yellow light at the position, so thatthe compression amount may be set in the range of 0.1 to 0.3 μm. Thatis, the height of the supporting structure 102 is slightly higher thanthe distance between the flat layer 105 and the metal layer 201.

In addition, in the above display panel according to the embodiment ofthe present disclosure, as shown in FIG. 11 , the supporting structuremay further include: point-shaped spacers 102 b.

The point-shaped spacers 102 b are arranged in gaps between thestrip-shaped spacers 102 a.

In order to meet the requirement of the contact density of the spacers,the point-shaped spacers 102 b may also be arranged in the gaps betweenthe strip-shaped spacers 102 a, plane dimensions of the point-shapedspacers 102 b are smaller than those of the strip-shaped spacers 102 a,and thus the point-shaped spacers 102 b may be arranged at positionswith small spaces.

In addition, in order to reduce the influence on the rubbing alignmenttechnique, the strip-shaped spacers 102 a arranged regularly may beadopted preferably. In the figure, circles represent the point-shapedspacers 102 b, the shapes of the point-shaped spacers 102 b are notlimited, and in specific embodiment, the point-shaped spacers 102 b maybe in the shapes of circles, squares, triangles, etc.

Based on the same inventive concept, an embodiment of the presentdisclosure further provides a display device. The display device may beapplied to a mobile phone, a tablet computer, a television, a display, alaptop, a digital photo frame, a navigator and any product or componentwith a display function. Since the principle for solving problems of thedisplay device is similar to the above display panel, implementation ofthe display device may refer to implementation of the display panel, andrepeated parts are omitted herein.

Specifically, referring to FIG. 12 , the above display device accordingto the embodiment of the present disclosure includes: the above displaypanel and a backlight module located on one side of an incident surfaceof the display panel.

The backlight module includes a backlight source located on one side ofthe display device, that is, the backlight module is alaterally-incident backlight module. In FIG. 12 , a backlight source 304located in a first sub-region B1 includes a plurality of light sources305. Specifically, the light sources 305 may be light emitting diode(LED) light sources. In addition, generally, the backlight module mayfurther internally include a light guide plate. The backlight source inthe backlight module may be arranged on one side of the light guideplate, and light rays of the backlight source may be emitted in a way ofan area light source through the light guide plate, so that a lightsource is provided for the display panel.

In practical application, in order to avoid the situation that the lightrays emitted by the backlight source 304 penetrate through a non-displayregion and are conducted into positions of edges of a display region,such that light leaks from the positions of the edges of the displayregion, underlaying structure may have at least two followingarrangement manners:

Manner 1:

Referring to FIG. 5 and FIG. 6 at the same time, the underlayingstructure corresponding to the side where the backlight source islocated includes at least two laminated color resistor structures, sincethe color resistor structures are located on the same layer and made ofthe same material with a color light filter layer in the display region,the color resistor structures also have a light filter effect and mayweaken light intensity of the light rays penetrating through the colorresistor structures, and the color resistor structures may furtherweaken the light intensity of the light rays penetrating through theunderlaying structure after being laminated, or may completely absorbthe light rays emitted to the underlaying structure to relieve a lightleakage phenomenon.

The underlaying structure shown in FIG. 5 includes a color resistorstructure 101 a, a color resistor structure 101 b and a color resistorstructure 101 c which are laminated, and since the color resistorstructures 101 a, 101 b and 101 c are respectively located on the samelayer and made of the same material with sub-pixel color resistors inred, sub-pixel color resistors in blue and sub-pixel color resistors ingreen, after the light rays emitted to the underlaying structurepenetrate through the color resistor structure 101 c, only green lightrays can be emitted, and red and blue light rays will be absorbed by thecolor resistor structure 101 a. The green light rays penetrate throughthe color resistor structure 101 c and then are emitted to the colorresistor structure 101 b, only the blue light rays can penetrate throughthe color resistor structure 101 b, so the light rays cannot penetratethrough the color resistor structure 101 b, and the underlayingstructure is made to play a shading effect. The shading principle of theunderlaying structure in the display panel shown in FIG. 6 is similar tothat of the FIG. 5 , which is omitted herein.

Manner 2:

The underlaying structure corresponding to the side where the backlightsource is located includes one color resistor structure. Similar to theshading principle in the manner 1, when the underlaying structure onlyincludes one color resistor structure, since the color resistorstructure has the light filter effect, the color resistor structure mayweaken the light intensity of the light rays penetrating through thecolor resistor structure.

Specifically, because eyes of people are relatively sensitive to greenlight, the color resistor structure in the underlaying structure may bearranged to be located on the same layer and made of the same materialwith sub-pixel color resistors in red or in blue, and thus the colorresistor structure may remove green light rays by filtering to achievethe effect of relieving light leakage.

In the display panel and the display device according to the embodimentsof the present disclosure, the underlaying structure and the supportingstructure are arranged in the non-display region on at least one side ofthe display region, and the underlaying structure can underlay thesupporting structure, so that the supporting capacity at the non-displayregion of the display panel is improved, the external force impactresistance at the non-display region of the display panel is improved,and the light leakage phenomenon at the edges of the display region isreduced. In addition, since the color resistor structures are located onthe same layer and made of the same material with the color light filterlayer in the display region, the color resistor structures also have thelight filter effect and may weaken the light intensity of the light rayspenetrating through the color resistor structures, and the colorresistor structures may further weaken the light intensity of the lightrays penetrating through the underlaying structure after beinglaminated, or may completely absorb the light rays emitted to theunderlaying structure to relieve the light leakage phenomenon.
